Good morning, I am trying to restore the above teleprinter but have encountered a problem with the latch release mechanism. 4 of the latch release bars work properly but the 5th doesn't, this is the back bar that resets the far back coding bar. There is a sliding adjustment that moves all the latch bars but I can't find how to align just the 5th one. I have seen information in the instructions that refers to an eccentric. However I can't locate this, I think it might be hidden behind the tape punch unit, but not sure. Any advice would be greatly appreciated. Steve

Message-ID: <A35001A8-6B59-43C6-9976-93835EC18AE2@junknet.net>

Hey all, for those that created the last batch of RTTY files, would it be possible to create some different test files? Im hoping to be demoing RTTY on a variety of devices in a couple weeks at VCF East in NJ. (Whys this PA guy always in Jersey??)

And apologies if samples were already created, but could we get ones made from the RTTY wiki? Preferably...

Single page ish (wiki overview only?)

Overview + History + Early Amateur history combined

(If time permits - entire RTTY wiki)

I think those would be cool, both 170 and 850, but if time is tight preferred 170 for now as these will be used on mostly amateur gear and TNCs. Pray all this old junk works LOL.

I can prob make them but Im trying to piece together a large pile of tras..GEAR and get it all working, like what I do at the ship, so time is tight between this and my full time job. This would be a huge help plus Id like to use them at the ship as smaller files. Plus Id use fldigi and I think you guys were scripting them.

And yes if I can fit it all in my car, a Model 32 will hopefully be tagging along.

Can you send the URL of the desired text? I can have a look at creating an
AFSK file.

I remember someone posted an online AFSK generator where you could paste
in text and get an audio file back, but I have not found it yet (I should
add that to my page at https://w6iwi.org/rtty/audio/ .

While looking, I did find a page to generate news feeds off RSS plus an
art generator at https://unluckyfett.github.io/TTY-FEED-GENERATOR/ . I'll
add those to my audio page...

Jeff,
I've been off on other projects for quite a while, but still available 
are the files at:

https://5bits.net

Some are pretty long, but nicely allow you to take lengthy lunch breaks.

Enjoy!

Ah very cool I didn't realize there was a lot more (or I did and that was 6
months and 12,295 projects and family catastrophes ago).

@Harold Hallikainen <harold at w6iwi.org> this was the article/WIKI I think
would be cool in John's collection:
https://en.wikipedia.org/wiki/Radioteletype#

Since this demo/exhibit is sort of around amateur radio history as opposed
to the the ship, thats why I thought it would be a good fit, but not like
someone is going to sit there and read it. (I could be wrong). I think the
history section is neat because I've yet to find otherwise that RTTY really
spearheaded the other digital modes in amateur radio. It would have
happened sooner or later anyway, but it started with RTTY (well after cw I
guess).

and @John Spigel <w1an.dxusa at gmail.com> the ships TTYs have gotten a LOT of
exercise printing your Battleship NJ files; sometimes I let them play and
come back later. The final prints can reach across the room! Every single
time I run these things, people are very surprised to see them actually
working at the ship, and I should look at social media because nearly
everybody immediately pulls out their phones and tapes them printing.
Usually I'll pop open #2 (one of the ASR dometops) to let them see the
12,000 moving parts inside. (All this is in addition to letting kids type
their names on the other dometop that punches a paper tape for them).

I gotta swap our mini-me (the 28 compact) in there with the one Nick gave
me so we can have them chat over loop; life has just been a bit tough
lately so getting there has been spotty.

Minimodem is VERY flexible. I used it to create a 10bps ultrasonic FSK
signal (20 kHz center frequency) for transmission into a big room to be
picked up by devices in the room to tell them which room they are in.

Helping clean out a silent key estate and found some RTTY equipment.  This stuff is gonna go cheap and I can deliver to Hamvention for free. Equipment is in the St. Louis area so pickup is an option for those who are not too far.   I don?t recognize the tape puncher.  Maybe someone on this list will.  How about $25 for each piece?
  
I have not tested any of this equipment and won?t be able to do so before Dayton.  There is a lot of stuff in this basement and I?m trying to stay one step ahead of 1-800-GOT-JUNK.

Is that a model 35 ROTR reperf? I see many M28 ROTR similarities, but it
looks like 1? tape.

Subject: [GreenKeys] 28ASR typing unit issue
Message-ID: <7539beda-3d46-43f1-a681-4a60b93a3b9b@gmail.com>

Gang,

Referencing the attached pics, I ran across a mechanical problem with my 
28asr typing unit, that the code bars were changing with the data, but 
the main shaft clutch was not engaging rendering the type box 
inoperative. Upon inspection on the left side of the typing unit I found 
a loose screw that retaining a small flimsy tab that engages the left 
end of the top code bar, the "suppression code bar". The tab had lifted 
out of the small slot at the end of the suppression code bar, allowing 
it to move to the left disengaging a lever that permits the clutch to 
engage on the main clutch below. All is working now, but I'm at a loss 
for the purpose of this tab. Is it some kind of maintenance link? I have 
not found any reference to it in my manuals. Any thoughts are welcome.

Thanks in advance,

ken

The name says it all !!  "Print Suppression" 

Most likely used when numerous 'stations' are 
all on the same network, but admin doesn't want 
them to print any traffic not addressed to that 
specific station ...  decision to suppress or not 
suppress probably done by stunt box coding.

The tab is used to disable remotely operated print enable.
An option provides a solenoidt to operate the suppression code bar and
the tab will go into place to disable the magnet's operation. So put
the tab in place and forget about it.....

Officially, that little lever that holds the print suppression code
bar in the "printing" position is the 154650 Clip

Gang,

Has anyone built an equivalent LED tuning indicator for the Dovetron 
mpc-1000 series, similar or simpler, to the SSD-100K.

Thanks,

That's a clever circuit! I use a small XY scope on my Flesher TU-170. The
scope is

/Here is something I wrote a few years ago about the HD-3006 and some 
pictures:/

Here is a picture of a Heath "Crossfire" in action that I have been 
playing with. It is a solid state replacement for a CRT RTTY tuning 
indicator.

There is not much to it, just two LM3915 logarithmic LED drivers and a 
bunch of LEDs. But when I first plugged it in to my ST-6, it didn't do 
anything, so I thought it was dead.

It wasn't dead, just not very sensitive. I think it may have been 
designed for tube-type TUs with lots of output available on the "Scope"? 
connections.? The other problem was that the ST-6 has a 1 Meg resistor 
in series with each "Scope" connection, so it gets loaded down if you 
are not driving high impedance scope plates. With the HD-3006 internal 
pots set for maximum, I could only get about half the LEDs to light when 
driven by the ST-6.

Heath put in a diode detector to rectify the M & S tones going into the 
LM3915, but it is not really needed, as there is a detector in the 
LM3915.? So I bypassed D21 & D22 and removed C4 & C5. I also removed R2 
& R5 (180K across the input). With the HD-3006 internal pots at max, the 
ST-6 can now just barely drive the LEDs to maximum.

When receiving ITTY off the Internet, you don't need any tuning, so the 
HD-3006 isn't necessary. But when receiving off the air, it makes tuning 
the radio much easier than using the ST-6? "++ Meter."

Have fun,

Duncan

Ken & Group. [I've been a 'lurker' here on GreenKeys for a while now.
              I am not on the air at this time, but hope to change
              that soon.  A few minor health issues have been
              distracting me.]

I heard that Hank's son, [forgot his name; Jimmy?] inherited all of the unsold products,
sub=-assemblies and spare parts that were at the  DOVETRON  site at the time of Hank's
passing.  Or, maybe this 'stuff' was early on placed in some kind of storage facility.  

I cringe every time I see "Storage Wars", on the chance of seeing some  DOVETRON
boxes in one of those facilities.

I think that some or many of the 'west-coasters' should do what can be done to find
out Jimmy's passing date and hopefully an OBIT which might show some names of the
'half-sisters', related to Hank.  


That would likely be a good-sized amount of 'stuff'!  Sadly, Jimmy died himself.
I never heard the cause or situation that brought this about.  I don't know if
anything was ever sold out of the warehouse or storage facility shortly after Hank
passed away.

If I have been led astray on Jimmy's present status, I apologize.  If he should
still be with us, I imagine that he would certainly be interested in disposing of
much of that 'stuff'.  Otherwise, it might simply be auctioned off to someone
who knows nothing about electronics/RTTY/ etc.  

I am hoping that someone 'out west' might be able to do a bit of detective work
and maybe find some of the 'stuff' that would make many 'GREENKEYS' guys very
happy.

One thing that Hank designed, patented and sold was upgrade kits for guys
with a CRT during display.  The LED 'kit' was fairly simple and almost a 'plug
and play' thing for guys who knew which end of a soldering iron to hold onto.

One of my  DOVETRONS  got the upgrade kit, and with a bit of 'long distance
help' from Hank, it now works just fine.  One thing I was asked to do was to
send the CRT back to Hank so it might be made available to someone with a
dead or almost dead CRT tuning indicator.


For now,  73 to all,

Ralph - W8ROI - friend of Hanks.

Thats pretty cool,

But I couldn't help but notice that the Heathkit version was missing the
Tempest Intensity input :-) )

Message-ID: <SN7PR03MB7129CB054691B585EECBB99DFB252@SN7PR03MB7129.namprd03.prod.outlook.com>

Hello! I have recently gotten an AN/TGC-14(V) teletypewriter set and a TT-318/UG keyboard included free with it from a kind gentleman. I?m a part of the typewriter hobby, so it was mostly that aspect of teletypes/teletypewriters/teleprinters that interstested me. Now, I?m not electronically inclined, so I?m hoping that part won?t really need touching, though I?m expecting something may need to be there. I?ve already seen one of the patching jacks that wasn?t where it was meant to be. I?m basically clueless beyond watching a video and taking a cursory glance at the manual. And looking at the other things I could find.

I?d like to see the innards of this teletypewriter beyond what I?ve seen in manuals or of its sister machine, but after turning the fastener studs, the top of the front cover seems to be stuck. Any idea how I could release it? Also, would it be unwise to turn this machine on before hand turning the mainshaft, like the manual mentions? I was planning on hand winding it and checking the cables (which I?ve included a picture of. Do they look ok?) before any powering. The seller stated something needed a new rubber belt, but I have no idea whether that was meant for the teletypewriter or the keyboard. It did come after a keyboard message, though.

Continuing on about the keyboard, there seems to be rust on one of the gears I can see underneath and some sort of oxidation (? White rust?) on something else. Does the TT-318/UG use any electronics that I should be aware of? I couldn?t find much of anything on the keyboard alone. What would you all recommend for rust removal for anything? Evaporust? Naval Jelly? Nevr-Dull? I have a brass brush.

Where would I get paper when I eventually am able to use this machine?

For the last part for this long message, this specimen and its keyboard seem to have been contracted through the Teleprinter Corporation of Paramus, New Jersey, rather than the MITE Corporation of New Haven, Connecticut. Why is that? The contract number (am I reading that right?) is 71737 for both keyboard and teletypewriter if that matters. I also haven?t seen many, if any, AN/TGC-14(V)s. I see the AN/TGC-14A(V)s more.

I?ll try to get back to any responses in a timely manner. I thank everyone for their time!

Fabiolah,

Welcome to Greenkeys and the world of teletypewriters!

The MITE AN/TGC-14 family of machines is an interesting one, but is not 
the easiest to begin with, due to its compact size and signalling options.

To answer your last question first (its the easiest one!):? The 
company's original name was "Teleprinter Corp." and it was located in 
Paramus, NJ.? The original product was the "MITE" (Miniaturized 
Integrated Teletypewriter Equipment) and they got some interest (and 
possibly funding) from Western Union, who was looking for something 
simpler and cheaper than the Teletype Corp. Model 28. There were 
write-ups about it in the WU Technical Review, July 1957 and April 1958. 
But apparently they could not get the costs down to WU's level, so it 
was sold to the Military as a compact printer for field & aircraft use.? 
We have a AN/TGC-14(V) with a similar Teleprinter Corp. label at the 
Antique Wireless Association Communication Technologies Museum.? (I have 
had it running, though not recently.)? In 1961, the Teleprinter Corp. 
merged with Greist Manufacturing Co. of New Haven CT and the company 
name changed to Mite Corp. They produced various versions of small 
teletypewriters for the military, but by the late 1960s, they were out 
of business.
For more of the history and different versions, see 
https://web.archive.org/web/20221219121956/http://www.decadecounter.com/vta/articleview.php?item=128


The front cover should come off easily, but the unit was made to be 
waterproof, so there is probably a good seal behind the front cover.? 
Also the air pressure inside may be lower than your ambient. Look for a 
pressure relief valve on the cover or unscrew the cap for the cable 
connections to equalize the pressure.

You should not try to power it up until you have opened it and checked 
out the motor and cables.

The rubber belt in in the printer, not the keyboard.? You will have to 
inspect it first to see if it needs replacing.


There are no electronics in the keyboard.


Clean off any rust or oxidation and ensure all gears are well lubricated 
before applying power.

The Mite uses the same paper as all other teletypewriters, so there 
should be some available here on Greenkeys or on Ebay. All 
teletypewriters use standard typewriter ribbons, though some use special 
reels.


I have worked on the Mite machines and actually was trained on them in 
the Army 60 years ago, but have not done anything with them recently, so 
can't help much with specifics. But there are others on Greenkeys that 
have used them more recently.

Hope this helps,

Hello,

Thank you for the response, Duncan! You?ve given such great information! I?ll be reading and watching them all.

On the seal, I tried doing all you?ve suggested to loosen the seal and regulate the air pressure, and it hasn?t come undone. When I move it, I do see the cover moving, too, but not enough to want to release. They really made it quite tight! Am I meant to leave the valve open and/or cable cap off and wait? I didn?t and tried immediately.

Fabiolah

I just saw Duncan?s message about the seal and air pressure, so I now think it definitely should. Hopefully, lol.

Hello, once the two latches are turned it should pull and rotate down and off the front allowing you to pull the guts of the machine out on its tracks.  If you decide to sell it I would be interested, I am not sure where you are located.  The government often contracts parts and pieces to other companies so it is hard to say.

Fabiolah,

I haven't opened a Mite in years and don't remember exactly how it works 
and don't have one to look at here.? The pressure relief valve will work 
immediately. It may be that one of the latches is not released 
completely. If the cover and both latches feels loose, then it may just 
be the seal sticking some.

Duncan

Hello  Fabiolah

You may find CuriousMarc's short video on the MITE
<https://www.youtube.com/watch?v=U-1fwku4hOs&t=105s> to be of interest.
When you have it open, carefully look at the print hammer. Often the rubber
type material has perished and requires replacement. There are 3 parts in
this assembly, the hammer, a cylinder rod (1.6mm dia, 5mm length.) and the
faceplate (5mm x 5mm x 1mm). Mine was missing the last 2 parts and I am in
the middle of creating replacements. Also check the motor - I have seen
60Hz and 400Hz motors (for aircraft/ships). There should also be a set of
spare gears to change baud rate.
All the best with your restoration.

Gang,

One of my M28 typebox springs broke for a common character. I swapped 
out one from one of the rarely used characters, but would like to have 
it whole again. Does any one have any surplus to their needs?

Thanks,

Hello Bambi,


I have seen that video. It was before I got mine and is what made me want it even more, ha. I thought my front cover would come off that easily, but the seal is still giving me some trouble. I?ll be sure to take a look at the print hammer, like you said to! From one of the labels on the machine, the motor should be 60Hz, but I?ll be sure to check once I can. Thank you!


Now, this is addressed to you and anyone else who may have information. Flipping open the lift panel, I saw a cable with white spots that I think I?ve read about before, as I?ve seen it on the cables in one of my electric typewriters. It?s related to moisture reacting with the rubber hosing, right? Or wrong, lol. How would one go about replacing the rubber? Is it very involved? Does it hurt to leave it (or them, if I see any other rubber with the same affliction) like that? I don?t plan on doing it quite yet. I think I?ll be taking this one small step at a time. Thank you for your time!

Maybe they are just snooty because you have two wires sticking out of the front of your machine.  Do they all have Teletype logo plates on theirs?

I suppose you should check the HOA rules regarding proper teletype dress during outdoor exposures.

Hah! I wondered if that would get called out. I stuffed em back in there (taped up of course) and popped a plate on the front from my office 32. This one runs decent but the print head is in poor shape. Hoping I can swap my spare on.

For neighbors that wonder what all that stuff in the front yard is
(flagpole antenna, antenna tuner, elevated radials), I added a QR code on
the tuner cover. It can be scanned from the street and it takes them to

Gang,

I would like to fine tune the vertical relationship between the typebox 
and the curvature of the platen. All the characters print heavy on the 
top of the character, and the lower portion of the characters are much 
lighter, like the type box must be raised in relation to the curvature 
of the platen. Is there an adjustment to raise the type box and hammer 
mechanism simultaneously? A document and page number would be very 
helpful. I am loathe to start adjusting the wrong mechanism. Thanks in 
advance.

Here's one - a younger version of my buddy Harry who is now N9CQX, and 
who was then an officer with the River Forest IL Police Dep't.? ?He's 
posing in the dispatch area where a M28 KSR can be seen,? likely 
connected to what is now at least called the LEADS system.? ?He can't 
recall the purpose of the other machine that is partially visible behind 
the typewriter.? ?Maybe someone knows what model it is and what it might 
have been used for? - the blank panel on the right looks like where the 
dial would be on the later ASR-33 telex/twx machines? ? Harry said the 
real dispatch operator showed him how to punch a tape as a souvenir ;-)

Subject: [GreenKeys] Model 28 ASR short on current loop interface.
Message-ID: <CAAn781WBaEkAN4fLrgtKwSe66u1aZ1pssG5Pe-VzTyMYbLLfwA@mail.gmail.com>

Hello,

I have a model 28 ASR wired in half duplex. I had been successfully using
it with an interface I am building until it stopped operating. I measured
the resistance of the loop and it's a dead short. After unpluging
evreything from the Electrical Service Unit there is still a short on the
loop. I checked the coils and they are not shorted. I am not
very knowledgeable on the workings oif these machines apart from the
basics. Is there anything that come to mind that might be the source of my
problem?

Thanks,
Charlie Beck

Charlie,

Some units will put a short on the line when the power is off to the unit.

Good luck,

Army version, TT-5/YG.

It looks like a compact variant of a Model 19, which is
a Model 15 with paper tape gear on and the dial for
counting line length. It looks like the punch is
present but the transmitter-distributor to the left of the
unit, where there's a rubber pad it's missing.
Underneath looks like a loop supply, plus other
stuff which may or may not be related.

Heavy and awkward, like most Model 19 variants.

Doug is correct. That other TTY is a model 35. They connected those to the
SOS down in
Springfield, IL and they processed it further to NCIC in Washington DC.
I'm not sure what the 28 was used for at the time. He is in their radio
dispatch room. The squad car back then would radio in a license plate
number, the dispatch would type it into the 35 and a querry would come back
usually within a minute.

I worked on those between 1971 and 1978 for Western Union. My first year
was in Aurora, IL, then I moved on to Bloomington, IL. I did get a call
outside my area one time in Elgin, IL where the dispatch said "The keyboard
is shot" "bring another" - uh? Those 35 keyboards don't go out ever. Well
to my surprise the deputy on dispatch duty at 1am was dry firing, being
bored, and sure enough, he shot the damn keyboard. It had a huge hole in
it! LOL

Thanks Doug and Danny.? ?I have a vague recollection of the Model 35 but 
of course the model 33 was ubiquitous when I started messing with 
microcomputers in the 70s.? ?Although few hobbyists could afford them!

I know that ASCII was just starting to come into widespread use in the 
late 60s or early 70s when this photo was taken,? so it makes sense that 
it was connected to a more modern system.? ? The village of River Forest 
was quite wealthy, being the home of Paul Harvey, the founder of the 
Mars candy company, and numerous mobsters -? ?so they could afford all 
the newest toys ;-)

One thing to remember when looking at those TTY's. The baudot models had 3
rows of keys on the keyboard,
and the ASCII models have 4. Quite a few of the police stations had the
model 35 ASR. The electronics were
in the stand below and is what usually we were working on when we were
called to trouble shoot a problem.

When I went down state Illinois, I had about 3 IL State Police Radio
stations that had them, they were always
out in the boonies away from town. I think the Sheriffs had them as well.
They were later replaced by a small
computer looking terminal device called INCOTERM. It was actually a small
computer with magnetic core
memory. It required the operator to type in about 65 characters without
mistakes to boot across a network
from Springfield, IL State Police HQ. I never did see the local police pick
those computers up to replace the
model 35 ASR.  Hams were only allowed BAUDOT at the time, I did have an
'excess'  Model 33 teletype
hooked up for RTTY back then, but I used a home brew 8080 computer with a
translator program I wrote
to use BAUDOT on the air. (That's a nother whole story)

Thanks to qrpbuilder.com for suggesting exam table headrest paper as a substitute for TTY paper.? I built essentially the adapter he suggested, but I used cut-off chunks of the same PVC pipe to make the "cuffs" at the ends of the adapter instead of gorilla tape.

I've written up my experience here, with photos:
--?https://homepage.cs.uiowa.edu/~jones/pdp8/UI-8/log2026a.shtml#2026-04-21

This was a "just in time" situation, since we just got enough of our PDP-8 working that the console teletype is now useful for running things like ODT -- the octal debugging tool.  There's still something wrong, but debugging it will run through paper, and we only have most of one original roll in hand.  Now we can save that for the rare occasions when authentic TTY paper is called for.

My one complaint about the exam paper is that it doesn't tear off cleanly against the tear edge of the Model 33's plexiglass window.

I?m curious why you did not go with the link that Tom Tillson provided in the past for paper?  Does your teletype need a special type of paper?

Hello Wayne,nice to meet another WU tech here!

Yes, the State Police NCIC network was a dedicated line that usually ran
down to your Sec of State's office, that ran a query to your state SOS
database and if coded correctly, onto National NCIC in washing dc.

I remember being able to put a couple of characters in the queries and get
a "test" back that did NOT cause a "HIT" so the Police wouldn't
be notified that you were just testing.

In the beginning I liked the mechanical repairs of the TTY's but did not
like the electronics, the trouble shooting was something to be desired
if I remember correctly, but as I gained experience I was able to do ok
with it.

In around 1975 WU got a contract with a financial company and sent us to
IBM Selectric School. Someone built a relay device under the carriage
and their own electronic box as an interface. Interesting school v/s
Teletype - But the real nightmare was the mechanics of the form guide
contraption
on top of the selectric.

But but but ... sputter.  Teletypes are just as much digital devices as any modern computer.  The difference is that Teletypes (especially old ones) are mechanical, not electronic.  All those levers, push rods and whatnot are doing digital logic.

If someone wanted, it would be entirely possible to build a fully mechanical digital computer using the fundamental mechanisms of a Teletype.  The selector latches serial data into the 8 bits of a mechanical register.  The blocking levers transfer the data from this register to a data bus (the codebars).  The stunt box decodes the value in the code bars to enable stunts like CR and LF, while the typing mechanism decodes which character to type.

While the Teletype mechanism can do just about any logic you want, and it has a register in it, what it doesn't have is RAM.  Teletypes are even pipelined -- the selector mechanism is busily receiving the next character while the previous one is being printed.  From that perspective, the selector latches are the interstage register linking the receive pipeline stage to the print pipeline stage.  How cool is that!

*Holiday Visits With My Dad to The Teletype Machine That Could Draw*

There are memories that do not return as stories, but as textures. Sound
first. Then light. Then the quiet certainty that you were standing near
something important, even if you didn?t yet have the language to explain
why.

For me, the teletype was one of those things.

It sat in my father?s Wall Street office with a kind of earned authority,
not sleek, not hidden, not abstract, but solid and unapologetically
mechanical. It didn?t pretend to be silent or effortless. It announced
itself. You didn?t wonder whether it was working; you could hear it
working. From a child?s vantage point, it roared. The clatter of keys
striking paper, the staccato rhythm of metal meeting ink, the steady pulse
of information becoming physical in front of you. By modern standards it
was slow, but to me it felt immediate, alive, connected.

Holiday visits made the whole place feel different. Christmas. Easter.
Seasons when the trading floor carried a softened energy, when the adults
were still focused but somehow more reachable. I would follow my father
through the office, the smell of paper and ink, the low hum of
conversations I wasn?t yet part of, the suits and ties moving with purpose,
and then there it was: the machine that could draw.

That was the magic. The teletype didn?t just print numbers or quotes. It
created images out of nothing but characters. Line by line, it would summon
Santa and his sleigh, reindeer in formation, or an Easter bunny taking
shape as if the machine were thinking in its own language. You watched the
picture arrive in real time, each line a small act of creation, each pause
a moment of anticipation. The adults saw a tool. I saw something closer to
a living instrument.

Around it, the office felt like a world where everything revealed its
mechanism. Even the water cooler in the corner had its own quiet spectacle,
the heavy glass bottle inverted on its base, the slow rise of bubbles when
someone filled a cup, the tiny hesitation before the water settled again.
Nothing digital. Nothing hidden. Cause and effect right in front of you.

Looking back, what made those moments special wasn?t just the machine. It
was the transparency of the world around it. Communication had a sound.
Information had a physical form. Work had weight. Systems were visible. You
could see the process, hear the process, feel the process.

And as a child standing there during the holidays, I wasn?t thinking about
markets or infrastructure or the machinery of finance. I was simply
watching something unfold that felt bigger than me but not closed off from
me. The teletype didn?t hide its workings. It invited you to witness them.

That is what remains.

Not just the memory of a machine, but the memory of a world where
connection announced itself, where creation happened in plain sight, and
where a child could stand in the middle of it all and feel, even without
understanding, that this was something real.

I wonder if any of today's generally good OCR tools could successfully don this conversion.  I suspect that it would be faster to try hand transcription, as awful as that job sounds.  Someone did it 50 years ago to make the originals.

When I saw the title, however, my mind flashed back not to ASCII (or BAUDOT) art, but to the fax machine I remember seeing as a child when I visited the Museum of Science and Industry in Chicago.  They had two machines next to each other in what I recall looked like identical housings.  I'm pretty sure one was a Model 32 RO machine printing wire service text.  The other was a fax receiver printing weather maps.  Looking through the window on top, you could see a helical bar that was turning one turn per scan line behind the page while the paper advanced one scan line per turn of the helix.  The cloth ribbon ran full width between the page and bar that hammered the ribbon against the page and helix for each black pixel.

I stared at that machine for several minutes trying to figure out how it works.  The above description is from my memory so may be wrong.

In any case, that was definitely a TTY that could draw!

I don't know how useful or accurate this is, hopefully someone will 
correct me if I have a bad method.? I have seen these odd spots on 
rubber and plastic parts in my machines.? If the rubber is otherwise ok, 
I have been taking an exacto knife and very carefully and gently 
scraping the spots off.? When scraping I am using a magnifying light 
from a craft store.? I am using silicone oil or silicone grease on 
rubber to hopefully preserve these parts a bit.? Silicone based oils are 
better for rubber and plastics from my reading.? I have only needed to 
replace one rubber sheathing so far, and used modern shrink tube for 
this.? It does not look completely period correct, but this particular 
wire was fortunately out of sight normally.

I have seen video of typewriters with very badly aged rubber, I have 
been lucky with my devices that the rubber is generally in good shape.

Hi All.

I've digitized my former paper tape library of RTTY Art pictures and have
over one hundred examples here that include the one pictured on the
Teletype machine in the photo on the right.

Many date from as early as the 1950s and 1960s.

Here is one of my sources for RTTY Art:

Please, please please if at all possible pick it up, show the typing unit is properly secured. Also make sure that all of the plastic surfaces are well protected. I have had multiple 33s that got damaged or destroyed, despite best intentions by being transported in a vehicle. ??????

Mike and Hugh,

Sounds like fun.  Wish I could make it.  I'm not that far from Williamstown.  A straight shot right down route 7.

Been thru Pittsfield many times years ago traveling between Rutland VT area to Plainville, Connecticut.  Before the interstate was complete.  A long trip back then.

Too bad they don?t ship and I?m busy when the auction closes.
I?ve been wanting a 33 ASR. But it?s probably all as well,
as shipping could cost $700.

Hi folks, Does anyone have an original manual for the above receiver that
could be scanned for me?
All of the ones on the Web are from the same source where the front page
and all diagrams and drawings are very black and impossible to discern any
detail.
The number is T.O. 31R2-3BC639-22

Great photo!  thanks for sharing.

That tape perforator on the left I think is called a Teletype Model 14.
Western Union used them
all the time back when their offices were open. WU called them 2A/2B. (if
my memory serves me)

When I was in the USAF, I used the KWM2, Amplifier, and Console quite a
bit. They were available
in suitcases making them easy to transport. I had a measuring tape
dipole contraption manufactured
by Collins I took along also. I only took the Collins equipment to
operate ham radio, no USAF business
but the leaders didn't know that. LOL - I never had anyone question my use
of CW on these and
other Collins radio equipment. Occasionally I would operate SSB, one just
had to be careful who
was listening in the same area I was in.

I was trained in Ground Radio repair but soon was transferred into a combat
controller unit (TAC), and
followed the Army around all over which made it way easier to get away with
operating as a ham.

Great story Nick and Tom!

I've been back to printing some overstrike-art on my Model 33, and attached
here a few pictures that I hope may be of interest.

ASCII files attached in a zip -- these are in the ready-to-print format,
i.e. CR for return-only and then CRLF to advance to the next line.   The
large art prints take a very long time, of course.  Even at 110 baud on the
model 33 they are sloooow.  The emoji are much more approachable.

- Some of my favorite emoji:  "wave", "fish", "shark", "shell", "duck"
- artwork by Katherine Nash (1968) "Spheroids"
- artwork by Frederick Hammersley (1968-1970) "Tiddly Winks", "A Good
Line", "Jelly Centers"

"A Good Line" includes asterisk, which is in ITA2 but not Baudot, so I
don't know how that one will translate to ITTY.  (The Nash/Hammersley
originals were developed in Fortran on an EBCDIC mainframe and IBM
lineprinter, although these versions are my own recreations to fit a
72-character line).  The others should all be Baudot-safe.

If anyone prints them successfully I'd love to know!

Hugh

Hugh, thanks for posting. I've been working with some code to covert art 
files to MP3s. Not as easy as you might think. I've taken your ascii 
files and batched them to 5bit MP3s. Many ASCII characters don't 
translate to the 32 character limitations so you get what you get. Both 
170 and 850 shift. Do they work??? Beta test... Let me know! I plan on 
adding many more, properly titled and indexed.

The files are at https://5bits.net third column near bottom.

73, John W1AN

I'm close to this one!

It looks like it is a webcast auction, both in-person and online at the
same time (?). If I can figure out how this works by Friday, I'll see if I
can pick it up.

Thanks for sharing.

Based on the number of rows on the keyboard, is the left unit with the
telephone dial a 28 (Baudot), and the right one a 33? There's a note on
one of them saying they were from a print shop. A friend owned a
typesetting company, and he used punched tape to drive the
phototypesetting equipment.

OOPS! I guess I should read the subject line that says M32 an M33...

A mention of a "KSR-27 teletype" caught my attention in these memos on the
formation of the DEC Computer Museum in 1979. I'd never heard of this model and
I'm surprised it's not one of the more typical models used with a computer. Does
anyone know anything about the Model 27?

    PDP-4 #1

    1 central processor
    8K memory
    1 line printer (Analex)

    1 KSR-27 teletype
    1 paper tape reader/punch

This site on telegraph equipment says

    Model 27 - referenced in museum book - says that is the model number for
    TT-4/TG (XC-2) a proposed military machine with a typing unit like a Model
    26 and a keyboard like a Model 31.  Says only 10 units were made.  Note that
    the production TT-4/TG is a Kleinschmidt machine.

All I have is the 1946 Model 27 parts book, which does refer to it as
the TT-4/TG
https://www.navy-radio.com/manuals/tty/jh/ttyman8/TeletypeManuals/model27/1138B-Iss1.pdf

I presume that was just a typo for the "KSR-28" which is listed in all
the PDP-4 literature.

Hello, my name is Ole. I?m an amateur ham operator in the Portland Oregon
area. I recently have been looking into getting a teletype, specifically
the bigger asr model 28, with both printing and baudot capabilities. From
all the places I looked, there are no teletypes of any kind for sale in my
area. Which sorta sucks?

I decided to reach out to green keys to see if there is a way I can get a
hold of a teletype, hopefully a functional one.

Thanks, Ole

Paul,

Both Kleinschmidt Laboratories and Teletype Corp. bid and build 
prototypes for the US Signal Corps tactical teletypewriter, the TT-4/TG 
in the late 1940s.? Kleinschmidt got the contract in about 1950.

Teletype Corp. apparently gave their version the commercial name "Model 
27" (since it was similar to the M26), but it never went into production.

Have fun,

Duncan

Teletypes are incredibly interesting and fun to work with.? I have a M28 
KSR wall mount, M28 standard KSR, and just got an Army Signal Corps 
TT-4.? Not quite on the air yet, but getting there slowly but surely.

You likely already know the M28 ASR is really (really) big.

Expect several hours of study to understand them - I have spent a great 
deal of time with mine and still only have a shallow understanding of them.

As far a buying them, that isn't -straightforward- as such.? I found the 
M28KSR from facebook marketplace and I just got lucky I think.? The 
standard M28 I think was from a message here on Greenkeys.? The TT-4 
came from auction, but someone mentioned it here on Greenkeys.? Do some 
research on the type you might like and then just be on the lookout here 
and on the usual 'classified ads' websites.? There actually was an M28 
ASR for sale a few months back, so they do pop up from time to time.? Be 
open to getting a model that isnt specifically the one you are after.? 
For example I really am after the military models, but the M28s have 
really grown on me in the meantime.? The M28s have the advantage of 
fairly decent parts availability from Mr Rtty.

Here are some notes on my M28 project - Getting started with a teletype, 
my consolidated notes on restoration ? Stickelman.net
